Lysimachia plant named ‘Night Light’

ABSTRACT

A new and distinct cultivar of  Lysimachia  plant named ‘Night Light’, characterized by its dark yellow-colored flowers, dark green and dark burgundy colored foliage, having light green-colored venation; and moderately vigorous, mounded-spreading growth habit, is disclosed.

Latin name of genus and species of plant claimed: Lysimachia alfredii.

Variety denomination: ‘Night Light’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lysimachia plant botanically known as Lysimachia alfredii and hereinafter referred to by the cultivar name ‘Night Light’.

The new cultivar originated in a controlled breeding program in Hem, the Netherlands during July 2016. The objective of the breeding program was the development of Lysimachia cultivars for use as an accent plant in a container or a flowering groundcover in shade to partial shade landscapes.

The new Lysimachia cultivar is the result of self-pollination. The parent of the new cultivar is the proprietary Lysimachia alfredii breeding selection coded B009, not patented, characterized by its medium yellow-colored flowers, medium green-colored foliage having slightly darker green-colored venation, and vigorous, spreading-trailing growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated self-pollination during August 2017 in a controlled environment in Hem, the Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings since August 2017 in Hem, the Netherlands and West Chicago, Ill. has demonstrated that the new cultivar reproduces true-to-type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Night Light’ as a new and distinct cultivar of Lysimachia plant:

-   -   1. Dark yellow-colored flowers;     -   2. Dark green and dark burgundy colored foliage, having light         green-colored venation; and     -   3. Moderately vigorous, mounded-spreading growth habit.

Plants of the new cultivar differ from plants of the parent primarily in having darker green and dark burgundy colored foliage, having green and white venation, reduced growth vigor, and a more mounded growth habit.

Of the many commercially available Lysimachia cultivars, the most similar in comparison to the new cultivar is ‘Persian Chocolate’, not patented. However, in side-by-side comparison, plants of the new cultivar differ from plants of ‘Persian Chocolate’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have light, green-colored venation         unlike than plants of ‘Persian Chocolate’;     -   2. Plants of the new cultivar have a leaf color that has less         burgundy coloration under shade conditions than plants of         ‘Persian Chocolate’; and     -   3. Plants of the new cultivar are taller than plants of ‘Persian         Chocolate’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Night Light’. The plants were approximately 20 weeks old. The plants were grown three plants per pot in three-quart containers for approximately 12 weeks in an outdoor shade nursery in West Chicago, Ill. Plants were given two pinches prior to transplant and one pinch one week after transplant.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in August 2021 under natural light conditions in Naperville, Ill.

The following descriptions and measurements describe approximately 20-week old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown three plants per pot in three-quart containers for approximately 12 weeks in an outdoor shade nursery in West Chicago, Ill. Plants were given two pinches prior to transplant and one pinch one week after transplant. Prior to transplant plants were grown in liners in a poly-covered greenhouse in West Chicago, Ill. Greenhouse temperatures ranged from an average high of 79.5° F. (26.4° C.) to an average low of 68.5° F. (20.3° C.), and supplemental lighting was provided daily for five hours during short days. Measurements and numerical values represent averages of typical plants.
